Metal-salen derivatives of polyoxometalates crystalline material: A new inorganic-organic hybrid compound exhibiting photocatalytic properties

摘要

By combination of β-octamolybdate and Metal-Schiff-base complex, a new organic-inorganic hybrid compound Na2[Mn(Salen)(H2O)2]2[β-Mo8O26]·3H2O (1) (sa-len=N, N'-ethylene-bis(salicylideneiminate) has been successfully isolated. Compound 1 was structurally characterized by elemental analyses, IR spectra, thermogravimetric analysis, and single-crystal X-ray diffraction. Compound 1 represents a rare example of single-crystal structured of metal-Schiff-base derivatives of polyoxometalates(POMs). Photocatalytic experiment indicated that 1 exhibited high catalytic activity for photodegradation of RhB with UV irradiation.
